Emulsifiable Concentrates (EC)

In EC formulations active ingredient contents between 0.1 – 40 % can generally be realized, sometimes even up to 70%.

The pesticide is dissolved in a water-insoluble organic solvent. Together with emulsifying agents, the solution will form an emulsion when mixed with water.

For a long-term stable formulation, the correct HLB has to be obtained. The employed emulsifiers are often a pair of anionic/non-ionic surfactants.

Key-factors:

  • Pesticide must be soluble in water immiscible solvent
  • Correct HLB values need to be adjusted
  • Crystal formation has to be suppressed
